hello everybody

one of the sounds that should be recognized by the system is the walking sound. so that i search a study that full and simply caracterize the walking sound (frequency spectrum, amplitude,).

can any one help me

thank's
 

An easy case would be dress shoes hitting a hard floor...

Each tap will consist of a few up-and-down waveforms, which can look like anything ranging from noise to a sine wave. There may be a sound when the heel hits, and another when the toe portion hits a fraction of a second later.

The taps will be separated by a period of silence, generally between 0.3 and 1 second.

A step may create more than one tap: (1) when the shoe scuffs the floor in mid-stride, and (2) when the shoe lands.
